What Is FEOC and Why It’s Becoming a Deal-Breaker in Clean Energy Finance

You’ve probably seen the acronym floating around in deal memos and compliance checklists lately. FEOC. Foreign Entity of Concern. Six months ago, most people in the tax credit space treated it like background noise. Just another regulatory acronym to file away.

That was a mistake.

Because right now, FEOC status is quietly killing deals. Projects that looked bulletproof on paper are getting flagged. Credit buyers are walking away from transactions they’d have jumped on a year ago. And if you’re in the business of buying or selling clean energy tax credits under the Inflation Reduction Act, you can’t afford to treat this as someone else’s problem.

Where FEOC Rules Came From 

While the concept of Foreign Entity of Concern was introduced within the Inflation Reduction Act, the real work happened after its passing. The IRS and Treasury spent much of 2023 and 2024 clarifying what it meant, particularly in relation to Sections 30D and 45X of the Act. 

The gist? If an entity is owned by, controlled by, or just subject to the jurisdiction of governments like China, Russia, North Korea, or Iran, it gets the FEOC label. Sounds straightforward enough, right?

It’s not.

The definition reaches way beyond obvious cases. We’re talking about indirect control through licensing deals, board representation, and joint ventures where a foreign government holds 25% or more. One client I spoke to was surprised to learn that a third-tier component supplier in their battery chain had a JV structure that technically qualified. They only found out during a credit transfer negotiation. Nearly torpedoed the whole thing.

Why FEOC Creates Risk for Tax Credit Buyers 

Look, the tax credit transfer market is still relatively young. The IRA basically invented it. Projections had it moving tens of billions annually, and buyers (usually big corporates with fat tax bills) were lining up to purchase credits at a discount from developers.

Good deal for everyone. Until the supply chain questions started.

Because here’s what changed. A buyer can’t just evaluate the project’s financials anymore and call it a day. Now you’ve got to trace the entire supply chain. Every battery mineral. Every component manufacturer. You’re looking for any link to a prohibited foreign entity, and if you find one, the credit could be worthless. Not discounted. Worthless.

And the IRS has been pretty clear that “we didn’t know” isn’t a defense they’re interested in hearing.

A Quick Look at Where the Pain Lands

That table gives you the broad strokes, but the reality on the ground is messier. Proposed rules keep expanding the scope. Energy storage, mineral processing, even software running on grid infrastructure. The direction is clear: more scrutiny, not less.

China and the Uncomfortable Math

Nobody in the industry loves talking about this part, but you can’t avoid it. China controls something like 60% of global lithium mining and more than 75% of battery cell production, according to IEA figures. Those aren’t numbers you can engineer around overnight.

Some manufacturers saw this coming and started reshoring or diversifying supply chains back in 2022. They’re in decent shape. But plenty of others are scrambling, and you can see it playing out in the credit market. Projects with clean, verified supply chains are getting premium pricing. Projects with murky sourcing? Deep discounts at best. Total buyer rejection at worst.

The timeline makes things even tighter. Battery component restrictions under FEOC rules became fully enforceable in 2025 (critical minerals kicked in a year earlier). If your compliance documentation isn’t airtight by now, you’re already behind.

What You Should Actually Be Doing About This

Depends which side of the table you’re sitting on.

Buying credits? Your diligence process needs a whole new layer. Supplier attestations, ownership structure reviews against Treasury’s published lists, and probably outside counsel who actually lives in this regulatory world. Don’t cheap out on that last one.

Selling credits? The burden is on you to prove compliance before anyone asks. The market has shifted to a place where sellers without clear foreign entity documentation don’t get term sheets. Not weak term sheets. No term sheets.

Conclusion

FEOC compliance isn’t some box-checking exercise you hand off to a junior associate. It’s the variable that determines whether a credit is worth millions or worth nothing. In a market this size, with this much money moving, that’s not something you get to learn the hard way.

Think about what’s at stake here. The IRA opened up the largest clean energy incentive program in U.S. history. Transferable tax credits alone represent a multi-billion-dollar market that didn’t exist three years ago. That kind of money attracts serious players, and serious players don’t tolerate ambiguity in their deal structures. The moment a project’s supply chain raises even a whiff of foreign entity concern, the conversation shifts from pricing to rejection.

Whether you’re originating credits, buying them, or advising clients on either side, this is the new cost of doing business in clean energy finance. Ignore it, and you’re not just leaving money on the table. You’re betting your reputation on a supply chain you haven’t fully vetted. In a market moving this fast, with regulators watching this closely, that’s a bet nobody should be comfortable making.
